You really should not use a 45 degree flare tool for 37 degree fitting. Yes it will work, but your sealing area will be much smaller, and tightening "the SH&! out of the fitting" may damage the fitting,especially if you are using aluminum fittings. Granted the cheapest 37 degree tool I could find was around $100.00, but I'd rather pay that than have my car in flames.

Also, the hard line adaptors that do not require flaring are intended to be used for low pressure applications, like carburetors. They may be OK to use for this, but they make me a little nervous.

They are becoming more common, and I think are even found to be acceptable by the FAA in some applications, but when the Earl's and Aeroquip catalogs both mention that they are acceptable for lower pressure applications, I think twice. The Russell's catalog even says they are to be used with their aluminum tubing with no mention of being acceptable for use with steel tubing.

I could use a set of SS lines for my 944S but apparently no one makes them?? email me if I am wrong at peterk@wepc.us

I just found this and thought I should share it with you guys since you are going into this. It seems that a single flare on seamed tubing will eventually split the tube at the seam. You need to use a 37 double flair tool if you are going to use your stock hard lines.

Here is the link.

I still say the hose clamps are the way to go but each to his own. Still got them for $70 a set. Have not had one complaint yet.

This is a good discussion, guys! I've found a 37 degree flaring tool to borrow, but am intriqued by the single-vs.-double flare issue...
